Extremality of Gaussian quantum states.
We investigate Gaussian quantum states in view of their exceptional role within the space of all continuous variables states. A general method for deriving extremality results is provided and applied to entanglement measures, secret key distillation and the classical capacity of bosonic quantum channels. We prove that for every given covariance matrix the distillable secret key rate and the ent...
متن کاملExtremality for Gallager's Reliability Function $E_0$
We describe certain extremalities for Gallager’s E0 function evaluated under the uniform input distribution for binary input discrete memoryless channels. The results characterize the extremality of the E0(ρ) curves of the binary erasure channel and the binary symmetric channel among all the E0(ρ) curves that can be generated by the class of binary discrete memoryless channels whose E0(ρ) curve...
متن کاملQuasi-extremality for Control Systems
The main object of study will be the Hessian of the "input-output" map of a control system at a certain critical point (extremal of the system). Let us recall, therefore, the definition of the Hessian of a smooth map. Let r ~ § M be a smooth map of some smooth Banach manifold into a finite-dimensional manifold and let ~0 ~ ~. The differential of r at D0 is the linear map D$0~:TB0 ~ + T~(~0)M of...
متن کاملDiophantine Extremality of the Patterson Measure
We derive universal Diophantine properties for the Patterson measure μG associated with a convex cocompact Kleinian group G acting on (n + 1) -dimensional hyperbolic space. We show that μG is always a S -friendly measure, for every (G, μG) neglectable set S , and deduce that if G is of non-Fuchsian type then μG is an absolutely friendly measure in the sense of [7]. Consequently, by a result of ...
متن کاملExtremality conditions for isolated and dynamical horizons
A maximally rotating Kerr black hole is said to be extremal. In this paper we introduce the corresponding restrictions for isolated and dynamical horizons. These reduce to the standard notions for Kerr but in general do not require the horizon to be either stationary or rotationally symmetric. We consider physical implications and applications of these results. In particular we introduce a para...
